Electrochemical Noise Study on Corrosion of Low Carbon Pipeline Steel in Sour Solutions

Electrochemical Noise (EN) measurements for low carbon pipeline steel (X52) samples were carried out in 3.5% NaCl aqueous and NACE solutions. Both testing solutions were saturated with hydrogen sulphide (H 2 S) at 20 and 60 o C, under static conditions. EN data was analysed in the time domain. Parameter such as Electrochemical Noise Resistance (R n ) and Localization Index (LI) were determined from the analysis in the time domain. Also, R n...
